The chair shouldn't deny a member joining the TG as a non-voting member
Rights of Voting Members
Must be a non-voting member first and participate in 3 out of 5 consecutive conference calls. After the third conference call, member could request to become a voting member.
Member shall loose its voting member's right if no individual with voting authority on behalf of the member is present for 3 out of 5 consecutive meetings/conference calls
Wi-Fi Simple Config&Secure Task Group
Most (estimate 70-80%) of wireless networks never configure security features
Many companies develop and deploy different proprietary solution to enable simple and secure WLAN setup
Therefore Wi-Fi Alliance has formed the Simple Config Task Group(SCTG) to establish a standard easy and secure setup solution
User don't need to understand technology or make decision the user does not understand
Ex: SSID or WPA….etc
Focus on home/Small Business and Home Office (SOHO) Wi-Fi Networks. All settings should be automatically configured
This proposal should support WPA/WPA2-Personal encrypted wireless network as minimum requirements
Supporting WPA/WPA2-Enterprise networks is considered a plus
AD-HOC support is allowed and welcomed as an additional feature

Others expected
Cellular Convergence Task Group
Many converged devices launched without WFA certification
WFA visibility poor to Cellular handset manufacturers
Trade press contain rumors of public and non-public organizations, e.g. SCCAN & UMAC, creating specifications for convergence products
WFA Board believes the Alliance is the best place to address Wi-Fi aspects of converged product certification
Minimum expectations on WCC devices
indication of service availability wifi and cellular
user can select (or switch to) different RF access
basic call possible using WLAN, activated by the user
cellular call possible, activated by the user
voice quality is 'similar to cellular'
when active on one RF access, users can receive calls on it (without noticeable interference due to other RF channel operations)
throughput sufficient for intended uses of the device

Public Access Task Group
The same functional components can also support browser-based authentication (UAM)
1 The wireless station (STA) discovers an 802.11 access point (AP) and initiates a connection request
2 The AP (or a network authenticator) responds with a request for the STA identity.
3 The AP forwards the STA identity as an authentication request message to the local authentication server/proxy (AAA-V).
4 The AAA-V examines the STA identity and decides that this is a roaming user. It forwards the authentication request on to the AAA server of the home provider of that user (AAA-H) (often, but not necessarily, via an INT) based on the realm name specified in the STA identity.
5 The AAA-H authenticates the user via an EAP-based challenge-response method that runs end-to-end between the AAA-H and the STA. A local user database is consulted by AAA-H to verify the username and credential provided by the STA. The result of the authentication and session key material are communicated back to the AAA-V, AP, and STA.
6 The AP configures link-layer session keys and signals that the STA has been successfully authenticated. Prior to this time, the AP blocks any attempt by the STA to obtain an address or access the Internet.
7 The AAA-V sends accounting messages to AAA-H and possibly to a billing and settlement intermediary as well. When the STA disconnects, an accounting stop message is sent as the last message for that session. The billing and settlement components process the accounting data and generate charging and billing records. Depending upon the processing requirements of the billing/settlement components, AAA-V may also save the accounting records to a log file and send them in batch mode to the billing/settlement provider. Note that a billing/settlement intermediary may but will not necessarily also act as an aggregator for authentication. These are independent functions.
8 Charging records are exchanged between business entities involved in this scenario, and settlement occurs.
9 The home provider adds charges to the user's bill for the public WLAN usage.

QoS Task Group
QoS testing of WMM baseline and features shall be optional for devices seeking Wi-Fi certification.
The rationale for optional certification is that as only some applications need QoS functionality
Also recommend to the WFA Board to include certification of product interoperability with 802.11e optional mechanisms, specifically Automatic Power Save Delivery (APSD), Block Acknowledgement and …etc
WMM Baseline Requirements
Priority throughput differentiation achieved·
Priority throughput differentiation achieved in an environment with legacy traffic
Scheduled Access Requirements
Ability to grant and execute a schedule·
Ability to operate in DCF(Distributed Coordination Function) and EDCA(Enhanced Distributed Channel Access) environment·
Priority differentiation of traffic streams/flows; mechanism works in terms of throughput priority including background traffic

Voice over Wi-Fi
About the MRD view of Marketing TG
The Voice over Wi-Fi Marketing Task Group's overall objective was to complete this MRD to be used by a Technical Task Group to guide test plan development and by the Board of Directors to steer their Voice-related strategy discussions.
Some points in MRD
The call can be initiated using any of the following commonly used voice call protocols
SIP, H323, Skype
One voice call is set up with a 1Mb bandwidth stream of background traffic for home network
Twelve voice calls are set up with a 3 Mb bandwidth stream of background traffic for commercial voice
Any codec can be used.
compliant to the requirements of the underlying base Wi-Fi certification grant (i.e., 802.11a, 802.11g, 802.11b, WPA, dual band).
Application Specific Device Task Group
The definition of ASD
ASDs are 802.11 devices ,e.g., clients or access points, that cannot be tested under a standard Alliance test plan because they do not comply to the standard test configuration and/or because they are designed to perform a specific application.
